In this article convergence of Riesz fractional integral is studied by comparing the integrand where with certain functions. Variation of coordinates as well as complex analysis are used to prove the convergence. This enables us to use the comparison test of convergence widely.

This paper presents an empirical performance analysis of a wireless network of 802.11b technology. The system provides communications to fixed, portable and mobile users and offer substantial flexibility to both end-users and service providers. The basic purpose of this paper is to analyze the performance of a designed wireless network capable of sending high data rates by measurement of the power transmitted as a function of distance and calculation of the signal to noise ratio at the Rx input for different distances. In this paper we studied the behavior of transmitted signals in free space for 400m distance between two buildings, the experimental wireless data network is designed and tested for this purpose, the measurements shows the wireless coverage and throughput patterns for static and mobile users. We have discovered which channel parameters have the most significant impact on performance in actual local environment. The application used to perform all the experiments is typical of common applications that would use these protocols and network technologies.

The present work includes cooling load measurement in Iraq. One room located in Baqubah was the object of the study. The measurement was taken for the room in summer months of 2004 (i.e. in May, June, July, August & September). The area of test room was 15 m2 and 3 m ceiling height with medium weight construction specifications. The test room includes exterior east and west wall facing, un-conditioning adjacent space with an exterior roof, east window and an exterior west door. The air conditioner unit used in this work was a window type with a nominal capacity of 2 T.R. (7 kW). The theoretical cooling load was predicted by three methods of cooling load calculation, which are TFM, CLTD/SCL/CLF & TETD/TA methods. Measurement of cooling load showed that there is a large difference between the measured and predicted cooling load with all theoretical methods. The difference ranged from 33% to 40%. This large difference is appear because of the several season such as the air conditioner type, suffer environmental and the construction specification of the test room where it’s represent the Iraqi building and not exactly same as building specification tabulated in ASHRAE tables

The protection of information for long period time is very critical in many environments. One way of implementation this protection with high activity is RSA cryptosystem. In this paper the old algorithm of RSA system is showed. And for more complexity and to increase time of attack coding. A new coefficient is z has been added to generator function Φ(n) in additional to selected p and q witch are depended in old algorithm.Furthermore: A flowchart of this moderation is presented with corresponding Matlab program ,and for more illustration one mathematical example is employed here.

Two methods for the determination of lead in toothpaste were tested and compared. In the developed method (ETAAS), the toothpaste samples were dry-ashed with %10 magnesium nitrate and the resulting solution was injected directly into the graphite furnace using a combined platform and matrix-modification techniques for the determination of Pb in these samples. In British standard method, the toothpaste was slurred with ethanol, evaporated to dryness, dry-ashed and the resulting solution was extracted with APDC/MIBK system. The organic layer was aspirated into the FAAS. Several statistical tools were carried out for the developed method to evaluate its analytical performance (LDR, MDL, LOQ, and RSD) and ANOVA Results for the calibration graph have shown that the regression line was statistically valid. With a %95 CL there was no significant difference in mean between the two methods by applying a paired t-test. Two procedures (direct and standard additions) of the developed ETAAS method were compared and tested statistically with British standard method based on RBD using two-way ANOVA. The results were revealed that all these methods have no significant difference and statistically valid

This research explains how the terminological (lexicographic or semantic) analysis of concepts contrasts with the conceptual (ornomantic) approach. The two models complement each otherand shold be used together. The onomantic model produces a two- by- two table which identifies a logically necessary fourth concept (here called allonym) which completes the scheme containing homonyms and two types of heteronyms (homographs and homophones). Conventionally, however, only the word- to- meanings paradigm is followed, producing the illogical results generated by this example derived from world net. Some word game enthusiasts enjoy listing homonyms and heteronyms. Their lexicological focus is reflected in virtually all glossaries for special language.. they also follow the orthographic (semantic) paradigm, with only an occasional step towards the logical classification concept, as one see by viewing specialized glossaries. By the way

At a time when many of our children are over-scheduled and over-stressed , we must ask ourselves what roles literature can play in their lives ? For many years , modern realistic fiction has been considered the most popular genre among young readers , perhaps because it was closer to the lives they know and , therefore , easier to read . such realistic fiction whether regional or historical provides opportunities for people to live vicariously in times and places they cannot experience any other way . Yet , sometimes many of the classic stories for children exist in the realm of fancy because of the timeless quality of such tales . Things that are most real in life can best be conveyed through fancy . Those who care about children and their literature have an obligation to inform themselves of the best and the latest thinking about the constellation of topics that will enable them to bring the two together most successfully . Writers usually believe in the vision of peace we offer our children insisting that violence , a brutal expediency and war are inevitable to get maturity . Apparently , it seems that it is nice to talk to children , to sing to them and to write fancy books feeding their imagination with dreaming tales of their futurely lives . Children want to feel some good tales to enhance highest ideals and purest dreams , then we expect our children to outgrow what we have taught them

The art of language teaching is a highly skilled activity which needs a lot of attention to achieve success and get good results .There is an interest throughout the world concerning foreign language study . Many conferences are held every year in different places studying the fundamental aspects for improving teaching process . Language teaching is an activity which is done by the teacher in his interaction with his pupils in the classroom . Class management is a matter of how teachers work to make conditions suitable for different learning activities . The absence of class management will lead to many problems and frustrations facing teachers in the classroom . There are various factors and principles of class management and language learning at the primary stage . Each one of these factors and principles has an impartment role in the process of language learning. These factors and principles can be divided as follows :- 1- Human factors .2- Non-Human factors .3- The psychological principles, and 4- The educational principles . This paper will discuss in detail all these aspects to provide useful information to those who work in the field of language learning and teaching
